The Contribute or Pay Idea, Revisited

In 2003 the Jahia Collaborative Source License proposed a bargain: open the code to everyone, then ask commercial users to pay or contribute back.

A reader's binder on the culture of software licensing: the texts drafted to share source code while keeping it sustainable, from open source to collaborative source, shared source and the source-available family.

The four parts of the binder

The binder is kept under four dividers, busiest first.
